If you plan to snowbird with your rig, it's far easier to have service done down south. We have the same engine in our DP and get our service done in Phoenix (Tolleson) at Freightliner. Talk to Kirk Ault, the Custom Chassis Service Manager. Costs about $300 for the basic service, and you can park in their full-hookup RV area for free. Best service around, hands down. We make a point of it every winter. Not sure if you would be able to watch, but I don't think you'd be able to do it for less yourself in YYC.
